i Lette/rs Patent No. 10,557, (lated March" 8, 1870.

STOvE-PIPE DRUM.

The Schedule referred to' in these Letters Pat-ent and making part of the 1eme.

To all whom it mag/'concern Y.

Be it known that l, EDMUNDYD. ROBERTS, 'of the same, I will proceed to describe its construction and operation, referring to the drawings, in which the same letters indicate like parts in each of the figures.

The nature of' this invention consists oi a smoke and heat-chambexyhaving lixed' air-circulating tubes arranged therein, and smoke and heat-conducting pipes` leading into and from said chamber, whichare placed intermediate between the stove exit-smoke flange and the end of the `common smoker-conducting pipe, said smoke and heat-chamber being inclosed in an air-boxV having an'air induction, and hot-air ednction conducting-pipe to and from the same.

It also consists of a hotair' chamber or oven, arranged in combination therewith.

The object of this invention is to unite air with heat, which commonly passes off in the smoke-pipe, and thereby `render it available for heatin g ,adj oin in g apartments, Ste.

In the accompanying drawings- Figures 1 .and 2 are vertical sectonviews.

a is the smoke and heat-chamber, having a pipe or flange, b, designed to lit onto the stove smoke-exit pipe; also a pipe, c, extending upward out of said chamber, to connect with the common smoke-pipe.

Thischamber a is provided with vert-ical or horizontal air-circulating tubes d, (in number more or less, as desirable.)

This chamber is linclosed within an air-box, e, which is provided with Cold-'air induction-pipe j; and heatedair eduction-pipe g.'

h isaeoldair chamber, which cold air passes through the tubes d into the chamber i., and in its passage from the chamber h takes up the heat from the pipes or tubes d, thence through the conducting-pipes q into an adjoining apartment.

k is a door to the oven or hot-air chamber t'.

m is a shelf or grating arranged in the oven or'hotair chamber, upon which to place any article desirable.

u is a damper, or valve arranged vin the eductionpipe or conducting-tube g, s6 that when it is closed the entire heat may beccncentlated in the chamber i, and by opening said valve the heat may be conducted into au adjoining apartment.

The end plates o of the chamber at are provided with circular openings p, to allow the air t0 circulate through and around outside ofthe chamber a.

lt will be seen that by arranging the tubes el in a verticalposition, and so as to connect with the 'stove smoke-exit and its exitpipe, the heat and smoke may pass through saidv tubes, and the air circulate around them, instead of as before set forth. t 'By this improvement the otherwise waste heat will be expended andabsorbed by the air circulating in the chamber, and around the heating-tubes into the chamber t', where it can be used to great advantage for various purposes, or by opening the damper rtthe heated air may be conducted into other desirable apartments.

l I believeI have thus shown the nature, construction, and advantage of `this invention, so as to enable others skilled in the art to make and use the same therefrom.

What 1 claim, and'desireto secure by Letters Patent, is-

The smoke and heat-chamber a, with its tubes darranged within a Cold and hot-airchamber h and t, with the tubes f and g, substantially as set forth.

Also', in combination with the above, ahot-air cham? ber or oven t, substantially as set forth.
